3054 and 3056 Marine Generator Sets Caterpillar

Alarm Switches

Usage:

3054 CHN

The engines are equipped with alarms in order to alert the operator when undesirable operating conditions occur. When an alarm is activated, corrective measures must be made before the situation becomes an emergency.

Alarm systems are electrically operated. The operation of all electric alarms utilize components that actuate switches in a sensing unit. Alarms are set at critical operating temperatures, operating pressures, operating levels, or operating speeds.

The switch can be connected to a visual signal (lamp) and/or an audio signal (bell or horn). The signal will continue until the condition is corrected. The control panels for the engines are equipped with an audio alarm for the low oil pressure and an audio alarm for the high coolant temperature. The control panels for the engines are also equipped with a warning lamp for the low oil pressure and a warning lamp for the high coolant temperature. Refer to Operation and Maintenance Manual, "Control Panel" for the locations and types of warning lamps.
